About GitHub CLI extensions
Note: Extensions outside of GitHub Enterprise Server and GitHub CLI are not certified by GitHub Enterprise Server and are governed by separate terms of service, privacy policy, and support documentation. To mitigate risk when using third-party extensions, audit the source code of the extension before installing or updating the extension.
GitHub CLI extensions are custom GitHub CLI commands that anyone can create and use. For more information about how to create GitHub CLI extensions, see "Creating GitHub CLI extensions."
Extensions are locally installed and are scoped to the user. Therefore, if you access GitHub CLI from a different machine or another user accesses GitHub CLI from the same machine, the extension will not be available.
Finding extensions
You can find extensions by browsing repositories with the gh-extension topic.
Installing extensions
To install an extension, use the extensions install subcommand. Replace the repo parameter with the repository of the extension. You can use the full URL, such as https://github.com/octocat/gh-whoami, or just the owner and repository, such as octocat/gh-whoami.
If the owner and repository are used, gh will install the extension using the hostname to which gh is currently authenticated. The full URL format is useful when installing extensions from a different host. For example, users on GitHub Enterprise Server should use the full repository URL to install extensions from GitHub.com or any other host.
To install an extension in development from the current directory, use . as the value for the repo parameter.
gh extension install REPO
If you already have an extension by the same name installed, the command will fail. For example, if you have installed octocat/gh-whoami, you must uninstall it before installing hubot/gh-whoami.
Running an extension
When you have installed an extension, you run the extension as you would run a native GitHub CLI command, using gh EXTENSION-NAME. The EXTENSION-NAME is the name of the repository that contains the extension, minus the gh- prefix.
For example, if you installed the extension from the octocat/gh-whoami repository, you would run the extension with the following command.
gh whoami
You can usually find specific information about how to use an extension in the README of the repository that contains the extension.
Viewing installed extensions
To view all installed extensions, use the extensions list subcommand. The output will also tell you which extensions have updates available.
gh extension list
Updating extensions
To update an extension, use the extensions upgrade subcommand. Replace the extension parameter with the name of the extension.
gh extension upgrade EXTENSION
To update all installed extensions, use the --all flag.
gh extension upgrade --all
Uninstalling extensions
To uninstall an extension, use the extensions remove subcommand. Replace the extension parameter with the name of the extension.
gh extension remove EXTENSION
